Former three-term U.S. Sen. Birch Bayh died Thursday. According to CNN, the 91-year-old was suffering from multiple illnesses.
Bayh began his political career as a member of the Indiana state House. He won a U.S. Senate seat 1962.
During his tenure in the Senate, Bayh was involved with several major policies. He served as the principal author of two constitutional amendments, the 25th and the 26th. The 25th, which passed in 1967, involved the succession of the presidency and vice presidency, while the 26th, which passed in 1971, lowered the voting age from 21 to 18.
Bayh was also largely responsible for Title IX, which he co-sponsored with Rep. Edith Green. It was an amendment to a 1972 education act that said that no one could be excluded from education programs receiving federal funding on the basis of their sex.
Bayh lost his bid for a fourth Senate term to Dan Quayle in 1980 and went on to practice law and work as a lobbyist in Washington. His son, Evan Bayh, served as Indiana's secretary of state, then its governor, and finally as one of its U.S. senators in 1999.
